Hi Ana,
the results that you see are correct, you just have to include more
information for the interpretation.
If you need 3'UTR coordinates, please see the "genomic coding start/end"
as well as "Exon Chr Start (bp)" and "Exon Chr Start (bp)".
Basically, the "Genomic Coding Start/end" are the chromosomal
coordinates and follows the same coordinates as of Exon Chr Start/End
coordinates EXCEPT that for an EXON that partially contains UTR sequence
(5 prime or 3 prime). So in your example, the genomic coding start/end
would be the same as of Exon Chr Start/End EXCEPT for the last exon
where the genomic coding end is smaller than Exon Chr end as the rest of
the exon contains 3UTR sequence.
Also, where there is no 3'UTR/5'UTR start/end at all for a transcript,
that means zero length UTR sequence. Note that you might see in some
cases multiple entries for 3'UTR/5'UTR start/end which means that the
UTR sequence spans multiple exons. For this, you might want to look at
the "Exon Rank in Transcript" attribute as well.
HTH,
Syed

Hi again,
I forgot to mention that in some cases, for the same transcript. I retrieve
more than one “genomic coding end”.
See below. For these results, I entered a list of 11 transcripts belonging to
different genes.
Best regards,
Ana

Subject: 3’UTR start
Hi,
I would need to extract some information of gene structure. It is a long list
of genes so I thought that Biomart would be useful.
However, I see that some of the attributes I want, don’t retrieve anything for
the majority of the genes. i.e. 3’UTR start.
Basically, one of the major data I would need to extract is the position of the
stop codon (end of the genomic coding sequence) for a list of transcripts.
Could you give me any feedback, please?
Best regards,
ANa
